Section 4: GUARD FACILITIES
Sentry booths, gatehouses, and guard towers are an
integral part of a perimeter security system. Sentry booths and gatehouses
are the points where personnel and vehicle control and badge exchange
operations are conducted. Guard towers, properly designed and located around
a restricted area, increase the range of observation and enhance the response
of security personnel.
Related Criteria. MIL-HDBK-1013/1 designates four levels of
security protection for structure design: low, medium, high, and very high.
An associated design threat (attack tools or methods) along with the
penetration delay time and ballistic resistance required for design is given
for each level of protection. The determination of the category of security
required against ballistic threats is a local command decision, with the
exception of nuclear weapons storage sites. However, activity perimeter gate
entry control booths or gatehouses should be provided with ballistic and
medium threat level protection as a minimum.
Sentry Booths and Gatehouses. There are four levels of security
to which a structure may be designed. Each level thwarts a specific design
threat (low, medium, high, and very high). Similar to designing a security
fence or gate for a restricted area, design of a sentry booth or gatehouse
must begin with a physical site survey, evaluation of vehicular and pedestrian
flow during operational and peak hours, and a thorough analysis of access
control and security requirements contained in the Site Security Plan. In
addition, a thorough local area threat analysis will aid in the decision of
threat level design. For other than nuclear weapons storage sites, NAVFAC
P-80, Facility Planning Criteria provides general criteria for use when
designing sentry booths and gatehouses. Based upon these factors, basic
design criteria can be determined such as:
Maximum number of personnel required to be accommodated in
the structure to effect security requirements.
Ballistics and penetration resistance.
Electronic and gate control equipment requirements,
including location in the structure for optimum use by security personnel.
Requirement for, and location of gun ports.
Requirement for a rooftop fighting position with a parapet
wall and access from the interior of the structure.
Heating, ventilation, air conditioning (HVAC), and plumbing
